Harrison, who turns 35 in May, has yet to find a new team after two weeks on the free-agent market. The Ravens were thought to be a possible landing spot for the 2008 Defensive Player of the Year -- Harrison had a visit scheduled in Baltimore on Sunday -- but the team signed linebacker Elvis Dumervil to a five-year deal worth $35 million.

The Steelers released Harrison before the start of free agency when the two sides failed to renegotiate his contract. Harrison was due a $6.57 million salary in 2013 and more than $7.5 million in 2014.

Harrison missed the first three games of last season while recovering from knee surgery, but he finished the season with a team-leading six sacks.

Even if the team was interested in bringing Harrison back, it has limited cap space to work with. The Steelers will, however, get another $5.5 million in cap space for 2013 when Willie Colon's release becomes official in June.
